1856: The Charter Oak was an unusually large white oak tree growing from around the 12th or 13th century until it fell during a windstorm on this day in 1856. According to tradition, Connecticut's Royal Charter of 1662 was hidden within the hollow of the tree to thwart its confiscation by the English governor-general. The oak became a symbol of American independence and is commemorated on the Connecticut State Quarter. Click HERE for pictures of the tree from the Connecticut Historical Society.

1883: An estimated F5 tornado caused extensive damage to Rochester Minnesota on this day. The enormous roar was said to have warned most Rochester residents, as the massive funnel cut through the north side of town. Over 135 homes were destroyed, and another 200 damaged. Many of the 200 plus injuries were severe, and other deaths probably occurred but not listed as part of the 37 total mentioned. This damaging tornado eventually led to the formation of the Mayo Clinic. Click HERE for more information.
